Improved paddle-wheel



UNITED STATES PATENT OEEicEO JAMES GOODIER, OF CHESTER, AND J. F. KILSHAV, OF NEWT BRIGHTON, ENGLAND.

IMPROVED PADDLE-WHEEL.

Specification forming part of Letters Patent No 55,439, dated June 5, 1866.

To all whom it may concern:

Be 1t known that we, JAMEs GooDIER. of

lChester, in the county of Chester, miller, and

J oHN Fos'rEu KILsHAw, of New Brighton, in the aforesaid county of Chester, cordwainer, both in that part of her Britannie Majestys dominions called England, have invented certain new and useful Improved Means for Feathering the Paddles or Floats of Side Propellers for Navigable Vessels; and we do hereby declare that the following is a full and exact description of the construction and operation thereof, reference being had to the accompanying sheet of drawings, making a part of this specification, and the figures and letters of reference thereon--that is to say:

The class of side propellers which our improved means or mechanical parts are intended to operate is that in which the lines of the axes whereon the paddles or oats move extend radially from the line of -the main or driving shaft at or about right angles therefrom-that is to say, the paddles or floats are set to enter the water edgewise, the line of the edge of each as it enters being parallel to the keel of the ship, then made to turn or feather and offer their surfaces of greatest area to act on or displace Water, and thereafter to turn or feather back, so as to leave the water edgewise. The angle to which the paddles or floats are or may be made to feather when deepest in the water should be suitable to the build or shape of the ship. In ships with lines of average iineness, the propellers being in the usual positions at the sides, we have found an angle of thirty degrecs to the line of the keel to answer well.

The accompanying sheet of drawings shows our improved means in Working position with a propeller ofthe kind above mentioned. As such propeller is not in general use we will, that our invention may be more readily understood, describe it hereinafter.

Figure l is an elevation as seen when looking toward the side of a ship; Fig. 2, an elevation as seen when looking along the side of a ship, and Fig. 3 a vertical section of Fig. 2.

In all these views like letters denote the l same parts.

a represents part of a ship side to which a metal block or cam, Z1, is secured by bolts and nuts or other means. The driving-shaftcrests in and passes through b, and on its outer end there is secured, by keys or otherwise, the bosspieces (l d', from which the frame-arms c, fast.- cned by screw-boltsf, radiate. These arms e are fastened at`their outer ends to the rim or ring g-they might be forged with it in one piece.

Between el and d are recessed spaces for the inner ends of the paddles or oats 7L, and the outer ends restin bearings therefor, formed in the rim or ring g. It will be observed that the recessed spaces for or the inner bearings are between d and d', for convenience in shipi ping the paddles or oats h, but it will be obvious that el and d' might be made in one piece if openings Were made in the rim or ring g, such as could be secured when the paddles or floats were placed in position. The paddles or oats h can be made entirely of metal,or of part metal and part wood.

In the drawings, the three highest are constructed each with a solid axis passing from. end to end and with thin plates on each side, the parts being fastened together by throughrivets. In the one on the left part of the plates are cut away, and in the remaining four wood is used, the metal end pieces having palms, shown secured to the wood by through bolts or rivets. We prefer the construction first described, as the Water will be the lubricant used, if not for both outer and inner ends and bearings, at least for the former. -Such bearings (marked fi) may be made of hard wood-say lignum-vit.

To the paddles or floats, at their sides and laterally from their axes, there are secured gabs j 5 nuts are shown as the fastenings, but other means may be employed. Connectinglinks lc are shown, coupled by pins toy and to elbow-pieces l. These latter, where they pass through the openings in flange d, are of a rectangular or other angular form in transverse section, and the said openings are of like form, the object being to make these parts act as guides and prevent oblique strain.

The inner ends of l are provided with fric tion-rollers m to run in the groove An. The upper part of that groove follows the course of a true ring, while the lower portion diverges laterally from that form, lont it is obvious the shape might be varied. Parts j, la, Z, and m should be made of east-steel.

The operation of the parts is as follows: When the driving-shaft c is made to rotate the boss-pieces d and d', and all the parts oonneeted thereto, are carried round by and with it. The elbow-pieces Z, with their friction-rollers m, are compelled to run in the groove n, and as they approach the lowest point of the lateral diverging portion they are foreed to move outward, and by the links k and gabsj, push the paddles or oats to the angle at which they are set to feather, so as to take a good hold of the water and thereby propel the ship. So soon as the friction-rollers pass the lowest portion of n they, and the elbow-pieces l, links 7c, and gabs j, are drawn back, and the paddles or iloats 7L made to feather or move baek and leave the water edgewise.

Having now given a full and exaet description ol' our invention, and mentioned the materials of which we consider the parts should be made, we would have it understood that we do not confine ourselves to the use of the partieular material mentioned, nor to the eXaot proportions or disposition of all the parts, as many niodieations in detail might be made without departing from the leading` features of our invention.

What we claim asini proved means for feathering the paddles or floats of the kind herein described is The eam or piece l), with groove n, elbowpieces l, links 7c, and gabsj, arranged and operated substantially as herein specified.

Signed and sealed bythe said JAMES GOOD- IER and Jol-IN Fosrnn KrLsHAW, at Liverpool, in the eonnty ot' Lancaster, in the Kingdom of England, this 9th day of January, A. D. 1866.
